Title	Mobile inverted-repeat elements of the Tourist family are associated with the genes of many cereal grasses
Journal	Proceedings of the National Academy of Sciences, USA
Year	1994
Volume	91

Abstract	Tourist was originally described as a 128-bp insertion mutation in the maize wx-B2 allele Subsequent analysis revealed that Tourist elements are in the introns or flanking sequences of 11 maize genes and a single barley gene In this study we report that Tourist elements are frequently associated with the wild-type genes of two other grasses, rice and sorghum Six of 35 rice and 5 of 8 sorghum complete gene sequences reported to date contain Tourist elements Furthermore, 11 additional maize genes have been found to contain Tourist elements, bringing the current total of elements associated with maize genes to 23. Sequence comparison of Tourist elements has led to the identification of four subfamilies, designated A-D. Evidence is presented for the recent mobility of elements in three of these subfamilies and in three of the four grass species. These data suggest that Tourist elements are highly repetitive in the genomes of some and perhaps all members of the grasses.
